The Tonking Kite

Fig.1 larger view

As its name implies, this kite is of eastern origin. It has a very simple structure, about which brief comment may be made. First, it is light in weight, because there is a broad wing or cover area with a minimum of framework. This is known as low wing load­ing, and it is important if the kite is to be successful in flight. Secondly, the kite is bow shaped. This upward inclination of the wing is known as positive dihedral. It improves stability; and in the third place, this stability is further aided by the use of a two-piece bridle, which provides side-to-side balance. Fourthly, the extended backbone permits the effective bracing of the framework.

The framework is formed by three strips, comprising a back­bone, A, and two crossbars, B and C (Fig. 1). The backbone is 2 ft. in length and is cut from 1/4 in. square hard stripwood. It is notched at the ends in the manner shown at D (Fig. 1). This piece should be straight and smooth and fres from knots or splits. The crossbars are each 2 ft. in length, and are made from split cane, about 1/4 in. thick. Failing this, 1/4 in. square stripwood may be used, though it is not so strong or flexible as cane. The crossbars are also notched at the ends (E, Fig. 1). These notches are for the bracing strings, which are added later.

The crossbars are now shaped to a curve. The method of doing this is described in Chapter 7 under the heading 'Shaping Wood and Cane'. The depth of the curve at the centre is 2 in., and the crossbars are held in shape by bowstrings, after the manner of making a bow for archery. The bowstrings should be taut, otherwise the crossbars may spring out of shape.

Secure the crossbars to the backbone, 3 in. from each end. The bowstrings lie clear of the framework on the underside. Use glue and strong thread to make the joints, and make sure that these are really firm and do not move from side to side.

The framework is braced with thin strong string. See the notes on string for kites in Chapter 7 under the heading 'Materials'. Begin by tying the string to the top of the backbone, and pass it in turn round the ends of the framework. Bring it back to the top of the backbone, and tie securely. There should be an even tension on the string, but do not bend any part of the framework to secure this. The backbone must be straight and the crossbars parallel to each other, if the kite is to fly successfully.
